Please help me to write a class file?

Hi;
I want to write a class that
after i input an integer say X in a dialog, it will calculate and display the answer of 2 raised to power X. The smallest value of X my program need to handle is 0. Teach me please!

Which part of the program you need help with? Is it the interface, the actual calculation, the compilation, the editing ... etc.
I don't think you're asking someone to do the whole program for you. Be a little more specific in:
1. What you have tried so far
2. What's not working ...
3. What you don't understand and need clarification with ... etc.
4. Do you have an education in Java ... how about in programming ...
The question, as you posted, is just too vague ...
But then again ... its quite possible that someone will post an entire solution for you ....
Good Luck
Kamran

Please help me, I mistakenly deleted a file. How can I retrieve my file?

PLease help me retrieve my file. I was rearranging some docs into sub-files and mistakenly deleted the main file, thinking the sub-files would still be there and they are all gone. Lots and lots of docs. PLEASE HELP ME,!!! The File name was "Cardis, Jackets, Ponchos& Tops Patterns. I was using the new Adobe Acrobat Reader.

I don't believe you can if the only copy is on your iPad.
You must make backups of files which you have on your mobile devices. Then restore from the backup. Backups could easily made by uploading them to Document Cloud, or backing up to another device.

Please help me to write a file from applet to server with a servlet.

In an applet the client elaborates a string and stores it in the variable of the name "line"
I would Like to write the string "line" in the file myfile.txt on the server.
I am in an applet trying to make the URLconnection to a servlet.
The part of the applet which calls the servlet is the following:
private void writeToSer(String line)
try
URL u = new URL("http://192.168.1.103:8180/servlet/ScriviFileServletFor1?stringa="+line);
HttpURLConnection urlConn = (HttpURLConnection)u.openConnection();
catch(IOException ioe)
JOptionPane.showMessageDialog(null,"IO Exception ","attenzione",JOptionPane.ERROR_MESSAGE );
the code of the servlet is the following:
import java.io.*;
import java.io.File;
import javax.servlet.*;
import javax.servlet.http.*;
public class ScriviFileServletFor1 extends HttpServlet {
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//read the parameters
String string = request.getParameter("stringa");
try {
File file = new File("/home/icurrado/myfile.txt");
FileWriter out = new FileWriter(file);
out.write(string);
out.close();
catch (Exception e) {
e.printStackTrace();
When I call the servlet from the bar of the URL with :
http://localhost:8180/servlet/ScriviFileServletFor1?stringa=prova
It works and writes the string "prova" in the file "/home/icurrado/myfile.txt".
When I call the servlet from the applet it doesn't work and it doesn't write the string in the file.
What is wrong or is missing ?
Please help me.

You dont need to go through the URL mechanism.
From an Applet you can directly save the file on the server at destinated location.
You can look for "Uploader Applet" in google.

created the interface and executed,it went through fine,4 rows data transformed into target xml data store,file is generated in the given path .
But in the generated file is same as which have EMPDEPT.xml with data change,but in the target xml data store depart i am able to view newly inserted records.
i want generate an output xml for each of the target of the XML data store, how we can do that please explain me.

Please help me recover a lost PDF file from Adobe Reader XI

Hi,
I was filling out a VA form 5655 in Adobe, and twice today, I lost my file and I just cannot type all of this stuff again, because I had to do so much math and typing and more math. All of a sudden "bloop", it was gone. When I try to go into file, then revert, revert is not highlighted. I tried pulling up history and it said there was no history. I just don't know what else to do, and I need this for the morning. Please help? Thanks

Hi Pat,
I filled it out directly from the blank PDF online, and never got a chance
to save the whole document. I did however save it about 1/2 way through,
but yet cannot find that 1/2 of the document either. Thanks.

Please help! My Itunes says corrupt file and will not open (IMac 2010). I couldn't fix it by reinstalling so I moved it to trash. It will not delete from my trash as it is saying "Japanese.lproj" is in use. I can't delete or open to close it, what do I do

Please help!
My Itunes says there is a corrupt file and will not open (IMac 2010). I couldn't fix it by reinstalling ITunes so I moved ITunes to trash. It will not delete from my trash as it is saying "Japanese.lproj" is in use. I have never opened or used "Japanese.lproj". I can't delete ITunes or open ITunes to close the Japanese.lproj, what do I do? Thank you for any help you can provide..

It will not delete from my trash as it is saying "Japanese.lproj" is in use. I have never opened or used "Japanese.lproj".
Interesting. This sort of thing is more common on Windows systems. Taken at face value, one of the iTunes program files (one of the Japanese language resources) is damaged.
I'd try running your Disk Utility over your startup disk. Does it find/repair any damage? If so can you empty your trash and reinstall your iTunes successfully now?

Please help! I can't open files in Photoshop 2014.2

I installed (and reinstalled and rebooted ad nauseum) Photoshop 2014.2 and now I can't open any files in Photoshop. When I click on a file in Bridge or in File Explorer, Photoshop will open but the file won't open.
I'm running Windows 8.1. I've updated my graphics card driver. My files aren't corrupt, because I can open them on 2014 on my laptop. Please, please help! I'm dead in the water and this is my business!

What have you done for trouble.shooting other than re-installing (which would probably be pretty much moot anyway if one does not uninstall and use the clean script first)?

Please Help Updating FCPX 10.0.8 files to 10.1.1 - Manually Doesn't Work

Hello all,
I tried updating all my Events and Projects from FCP 10.1.1 after using it for awhile (explanation below) and it won't recognize them. After studying online, I've put my Final Cut Events and FC Projects folders in my boot internal Movies drive and on the boot of one of my external drives, but still FCP X 10.1.1 won't recognize them - they are visible but greyed out.
I have been able to import media from those folders, but without the project files it would be back to the drawing board - no good.
When I first opened FCPX 10.1.1 I only updated 1 project - a full length doc I was working on, because I didn't want to clog the system while working,
(I had to get a Digital Cinema Print made quick on my system) and because after reading the Read Me First Notes and white papers, it made it clear that I could update my files manually later.
So far, no go. Please help. I'm of course - like everyone else - on a deadline, and I have at least 10 short films/projects that are in various stages of
edits that need to be completed.
Tom Wolsky, you out there? Kevin Monahan? It's been awhile since I needed advice. Yes, I know, operator error...so it goes. Please help anyone.
Working on an iMac (Late 2012) 3.1 GHz Intel Core i7 with 16BG 1600 Mhz DDR3 Ram on OSX 10.9.3.
Cheers and thanks to this community.
Juri

UUpdating updates volumes. You don't have to select the project or event. They will always be grayed out. Simply select the hard drive you want to update.
